POCKET-FRAME CLAMP FOR POOL-TABLES.

SPECIFICATION forming part of Letters Patent No. 365,849,- dated July 5, 1887.

Application filed October 527, i886. Serial No. 217,307.

(No model.)

nia, have invented a new and useful Improvementiu Pocket-Frame Clamps for Pool-Tables, of which the followingris a specification.

This invention relates to a certain new and useful improvement in clamp attachments to cushion-sections of billiard-tables,whereby the clamp is more easily and quickly adjusted to the pocket-frame and more firmly attached to the corner of the table in changing a billiardtable to a carrom-table.

Referring to the accompanying drawings, forming a part of this specificatiom'Figure 1, is a plan or top view of a pool-table with my clamp attached. Fig. 2 is a side view of the same.

Let A represent the clamp with its inner end pierced to receive the screw-threaded spindle a, provided with a stop, I), which limits the distance or penetration of this end of the screw to the corner of the table,and forms a shoulder upon the outer face, against which the inner face of the clamp is set. A milled-headed nut, c, is turned upon the outer end of the threaded screw against the outer face of this end of the clamp, and thus it is firmly held between the shoulder of the stop, milled-headed nut, and set-nut, and all side as well as end movement prevented. The clamp is divided centrally by a rule-joint, (I, so that the hook at the end of the clamp can be thrown backward or upward in adjusting the screw and nuts to the corner of the table and removing the clamp when changingthe table froma pool to a billiard table, and so constructed that the hooked end can be sprung down over the pocket-frame when the clamp is set in the corner of the table. In this position it is held by the fiat spring 6, the inner end of which is firmly fixed to the rigid end of the arm of the divided clamp. V

' In changing ordinary carromtables to billiard-tables, six of these cushion-sections are to be attached or detached, and this is accomplished with much loss of time and considerable difficulty where the ordinary clamp is employed, as the rigid arm or clamp is always in the way in adjusting the screw to the corners of the table. entirely overcome in the use of my improved clamp.

It is not my intention to claim herein the construction shown in Patents No. 132,084, October 8, 1872, and No. 241,9l3, May 24, 1881, and such construction is hereby disclai med.

Having thus described my improved clamp for billiard-tables, whatl claim, and desire to secure by Letters Patent, is-

In a pocket-frame clamp for pool-tablcs,the combination of the clamp A, jointed at d and having spring 6, and the screw-threaded spindle a, passing through the perforated end of the clamp A, and'having a stop, I), and the nut c, substantially as described.

In testimonythat I claim the foregoing I have hereunto set my hand and seal.
